When we know about measurement scales and distributions, we can decide on how to best describe our variables.

In this part, we go through a set of tables and graphs as well as measures of central tendency and variation.

We will first cover frequency tables. With regard to graphs, we will discuss bar charts, pie charts, and histograms.

For measures of central tendency, the mean, mode, and median are addressed. Moreover, some examples of measures of variation will be included here, namely minimum, maximum, variance, and standard deviation.

This part also includes a quite extensive section on epidemiological concepts, such as prevalence and incidence.

Finally, we end with a section on how to design informative tables and graphs for descriptive statistics.
